Insights into the Heat Shock Protein 70 (Hsp70) Family in and Its Roles in Response to Salt Stress.

Hsp70s, a group of heat shock proteins, are ancient proteins that play a crucial part in maintaining the stability of cells when faced with various internal and external stresses. In this research, there are 72 genes present and verified in , all of which exhibit a wide range of physicochemical characteristics. Through evolutionary analysis, the Hsp70 family was categorized into five primary groups, and numerous segmental duplications were anticipated among the genes. The GO enrichment analysis of co-expression network elements revealed a significant association between key signaling terms, such as phosphorelay signal transduction, and MAPK cascade with the function of . An analysis of transcriptome data exposed to cold, drought, salinity, and cadmium stress demonstrated the varied expression profiles of genes. The expression levels of genes varied across various organs and stages of development in camelina, although some of them illustrated tissue-specific expression. qRT-PCR analysis further disclosed that , -, and - were up-regulated and , -, and - showed down-regulation in response to salinity. Furthermore, genes are categorized as late-responsive elements to salinity stress. Through docking analysis, the current research revealed that CsHsp70 proteins interacted with ABA, BR, and MeJA.
